Liquid‐Phase Plasma Bubbles Exfoliation of Few‐LayerNanosheets for High‐Performance CO2‐to‐FormateConversion
Liquid‐Phase Plasma Bubbles Exfoliation of Few‐LayerNanosheets for High‐Performance CO2‐to‐FormateConversion
研究概述
利用液相等离子体气泡剥离Bi2Se3少层纳米片，避免外加插层分子并暴露较多不饱和键。CO2电还原制甲酸盐法拉第效率超过90%，稳定100小时；同一剥离方法还适用于MoS2、WS2和WSe2。
